PHNOM PENH - Housing rights activists demonstrated outside the Supreme Court on Tuesday, four days before judges there will decide on the case of Yorm Bopha, an activist whose supporters say she is being held without proper evidence.

Demonstrators burned some 100 arrest warrants already issued by the investigating judge, Te Sam Ang, who ordered the arrest of Yorm Bopha, 29, in August 2012.

The Court of Appeals in June upheld a lower court’s decision, finding her guilty of charges related to an attack on two motorcycle taxi drivers, charges her defenders say were made on weak evidence and in an apparent attempt to curb demonstrations by housing rights activists.

If the Supreme Court upholds the ruling, Yorm Bopha could remain in jail through September 2014.

Yorm Bopha’s husband, Lous Sakhon, said that he believes his wife is innocent and that she will be released soon.
